Like characters of reference are used throughk2 'out l'the "following "speciiication .and the :accompanying drawings to designate corresponding parts.

Incarrying outv the invention,"there is provided an improved non-plugging pump water closet having r'a horizontal operating vcylinder Isupported upon the spaced integrally formed depending legs 2 and 3 for supporting the watery closet elevated above the surface 4 upon V`'which vit -will bev` supported.

@ne -en'd of thev cylinder 'I 1-w'ill"be'open,an"d will'be'for'med with af peripheral ange 5 having `spaced threaded bolt vreceiving openings -6 extending therethrough. A circular closure-disk Lor'platel vv will be formed with similar spaced alignable bolt receiving openings `8, and will be removablyA secured upon the Aopen endof the cyl-l inder Iby means'of the bolts g-which are threaded through the aligned openings 6fand'8.

vtThe opposite endof thecylinder I is closedby `the head lwhich is formed'with'a centrally disposedbearing'boss Il,sai'd head'and boss being vcentrallyA andlongitudinally apertured'to'sidably receive fthe piston'rod I2 whose threadedl inner end extends throughthe'cupped head- I3of the piston t4', being "secured bymeansof' the nut I5 threaded upon the threaded'end of the'said pistonrod. A'glandil andpackingnut 'II willbe disposed within the bearing boss Il -about the pistonrod I2.

'A pair'ofspaced upwardlyangled bracketarms I 6 areformed uponithe jend closure hea'dpin, and'are provided with Kaligned 'apertures' through their `outer'endsto receive "the 'cross pin AI 1 `upon which the bell-'crank-piston 'rod actuatinglever i8is"pivotallysupported, having its 'flower end connectediby'means 'of Vthe cross, pin I 9 with the fork -`2li secured 4Vtorthe youter end `of :said rpiston krod I2.

'An vinwardlyextendingvertical"standard 2 I is lattachedto the vside of the 'cylinder I by-weld ing-arid 'is apertured at its upper end to'support the'cross pin 22, which in turn 'supports the forked'inner end 23 of the'actuating arm-24. A handle 25 is `secured 'tothe outer end of thea'ctuatin-g arm mi; and "zi-connecting rod' 'i5 is -connectedat its upper end intermediateV the ends 'of the tarmli, and is connected at its lowerend to the `upper end 'of' the bell crankV lever I 8, lwhereby a'reciproeatinr` upward and .downward movement of" the same'will Lcause the piston I 4' to.`move"`back andiforthin thelhcrizontal cylinder I for operatingfthe lWaiter closet.

vl-*vertical valve 'casing or cylinder 26wil1`be supported by the web 21 at the end ofthe cylinder I adjacent its closed end, and supports the valve 28 and connected rod or stem 29 for reciprocating movement therein. The rod or stem 29 extends through the lower end or the valve cylinder 26 and is packed by the gland 35. A bore 12 is formed through the web 21 between the valve cylinder 26 and the cylinder I so as to allow water to pass from the valve cylinder 28 to the cylinder I.

A pump operating arm 3l is pivotally supported upon the pin 32 attached to the leg 3, and a foot treadle 33 is disposed upon the outer end of said arm 3l. forked at 34 to overlie the arm 3i and is secured thereto by the cross pin 35 which extends through said forked portion 34 and through the arm 3l. A coil spring 35 will be disposed within the valve cylinder 26 about the rod or stem 29, and will lie beneath the valve 28 for normally holding the same in its uppermost position.

A water inlet pipe 31 will be connected between the side Wall o the valve cylinder 28 and the side of the boat (not shown)A at the point below the water line. An outlet pipe 3S will be connected with the annular flange 35 formed at-the top of the toilet bowl 49. Y v- The toilet bowl 4E! is provided with the usual cover 4I which is hinged at 52 at the rear end thereof.

The lower end of the toilet bowl 45 is reduced to provide the cylindrical portion 43 which terminates in the laterally extending annular flange 54, and the inwardly extending annular ange 45 providing the restricted outlet 45 for the bowl.

An annular seat 41 is formed below the inwardly extending annular flange 45, and supports the circular disk 48 in which the downwardly operating flap or check valve 45 is hinged, being attached to the flexible or resilient metal-spring strap 50, which is also attached to the disk 48. The disk 48 will seat inthe annular seat 41 and will also seat upon the upper surface of the annular ange I forme-d about the upper end of the bowl supporting vcollar 52 formed integrally with the horizontal cylinderl on its upper side and adjacent its open end.

The openings 53 will be formed through the disk 4S to receive the screw bolts 54 for securing the same within the annular seat 41 in the annular flange 45.

Openings 55 and 56 will be formed respectively through the laterally extending annular flange 44 and through the annular flange 5| for alignment with each other, and to receive the securing bolts 51 for holding the toilet bowl 45 upon the annular ilange 5I formed about the upper end of the bowl supporting collar 52 which is formed integrally with the horizontal cylinder I.

An offset outlet pipe 58 will be secured to the outlet opening 59 formed through the side wall of the cylinder I directly. below the connection from the toilet bowl 4U, and an outwardly opening one way flap or check valve Si! will be secured between said pipe 58 and said opening 59, and likewise a second outwardly opening one way flap or check valve 6I will be secured between the iianfe 52 on the outer end of the pipe 58 and the flange 63 about the adjacent inner end of the discharge pipe 54 which extends to and through the side of the boat (not shown) and vbelow the water line. Bolts 65 will extend through the flanges 52 and 63 to form a tight joint between the pipes 58 and 64.

In operation, the valve 28 and valve cylinder 2S serve as a controlling valve. When the pedal 33 isV depressed, it lowers the valve 28 in the valve The lower end of the piston rod 29 is cylinder 26 exposing the water intake and lets water in through the pipe 31 into the valve cylinder 25 and through the bore 12, into the cylinder I. The valve 28 is lowered by pressing down on the pedal 33 and when in its lowered position, the action of the piston I4 moving'inwardly towards the plate 1 pumps water from pipe 31 into the cylinder I through said bore or opening 12. After the water is drawn into the cylinder I by the piston I4, the return stroke of piston I4 will drive the water out of the cylinder I through the bore 12 into the valve -cylinder 26 and through the pipe 38 into the rim of the bowl 4, ilushing the contents which will rst move from the toilet bowl 59 into the cylinder I, and will then be discharged past the ilap or check valves 6D and 6I and out through the pipes 58 and 64 into the water outside the boat (not shown) and below the water line. The portion or" the bore or opening 12 is such that it will be open and unobstructed at all times re- -gardless of the position of the piston 28.

From the foregoing description, it will be seen that therev has been devised and provided a simplied non-plugging pump water closet which will be highly eicient in operation, and relatively inexpensive to manufacture and produce.

While the preferred embodiment of the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in the detail of construction may be resorted to without departure from the spirit of the invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the Unite-d States is:

A non-plugging pump water closet comprising a horizontal cylinder, a piston and piston rod reciprocatingly slidable in said cylinder, means to actuate saidpiston, a toilet bowl connected to said horizontal cylinder, a web on said cylinder, a valve housing carried by said web, an inlet port in said valve housing, a lateral port connecting said valve housing and cylinder and disposed in said web, a valve reciprocatingly mounted in said housing and normally closing said inlet and lateral ports, means to operate said valve, an outlet pipe connected between said valve housing and said toilet bowl, a check valve between said toilet bowl and cylinder, discharge means for said Water closet, va vertical standard on the cylinder adjacent its closed end, said first-named means including a manually operable arm pivotally supported on said standard, a link depending therefrom and a bellcrank lever connected between said link and piston rod.
